Another compatibility issue comes from the TLS/SSL configuration options. In MongoDB 3 and MongoDB 4.0, in the configuration files for both mongod (MongoDB database daemon) and mongos (which is used to control a sharded cluster), you could add a series of options under the net.ssl (https://docs.mongodb.com/v4.0/reference/configuration-options/#net-ssl-options) key. As of MongoDB 4.2, these options are deprecated in favor of the net.tls options. The net.tls options have enhanced functionality compared with the net.ssl options. These are covered in detail in Chapter 11, Administering MongoDB Security.
